As previously revealed, the Orrery features a new quest to help the Mages Guild repair a defiled Imperial Orrery. Gamers will attempt to return some valuable parts stolen by bandits when they intercepted an Imperial shipment. The quest also features new powers for characters "based on the phases of the moons."

The download's price comes as a relief to gamers, many of whom were dismayed at the cost of the horse armor download. At 150 Marketplace points ($1.88), the Orrery is 100 points cheaper than the equine protection, which went for $2.50.
